No one's mentioned lack of cup holders yet? I'll do it:
Lack of cup holders.
It's the worst when you forget, and you go buy a milkshake to-go and then have no where to put it, leaving you to finish it before you can go driving again. It doesn't really work to put it between your legs, at least for me the steering wheel is too close, plus the incline of the seat makes it more likely whatever's in the cup will end up on my crotch one way or another.
